Dr Pepper recipe from youtube comments

Youtube user Gorillionaire says:
"The primary flavor compounds in Dr. Pepper are from Cherry and Cinnamon. Ditch the Raspberries and Prunes for a mix of Morello and Rainier cherries. Then replace the licorice root with Kola nut. Swap the citrus extracts for zest."

150g rainier cherries
